Title: Instrument for measuring vertical displacement of stage
Inventor: CHO TEIKO
IPC: G01D5/38
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To measure the displaced position of a stage with high accuracy over a wide range by utilizing a regular Fraunhofer diffraction phenomenon by making the widths of the transparent areas, opaque areas, reflecting areas, and absorbing areas of first and second scale glass plates equal to each other. SOLUTION: Since a mobile section 20 is interlocked with the vertical displacement of a stage 1, the relative position of a second scale glass plate 17 to a first scale glass plate 13 changes and the diffraction distribution of the light received by means of a light receiving section 23 after the light is reflected by a reflecting area 18 changes due to a Fraunhofer diffraction phenomenon. Namely, the waveform of the light periodically changes. Therefore, the current signal outputted from the light receiving section 23 has the AC component corresponding to the waveform of the light and a circuit section 30 counts the number of shaped waveforms corresponding to the periodical change of the waveform of the light. A computing element calculates the moving amount of the stage 1 from the counted signal and the grid repeating periods of the glass plates 13 and 17.  Then the movement error of the stage 1 is detected by comparing the moving amount with the desired moving amount of the state 1.

Title: Concrete block and manufacture thereof
Inventor: KAMAISHI TADAMI
IPC: E04C1/40
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To improve impact resistance and abrasion resistance of a concrete block by arranging a resin protective part being mixed with a reinforcing material and reacting/hardening even in the presence of moisture in a part or the whole of a surface of a concrete main body. SOLUTION: Resin mortar mixed with a reinforcing material is injected by a prescribed thickness into a mold, and before hardening resin, concrete is poured into from above it. The resin for forming a protective part 3 on a surface of a concrete main body 2 of a concrete block 1 formed in this way hardens even if moisture exists at hardening time. For example, a polysulfide modified resin is suitable. The polysulfide modified resin is excellent in an adhesive property and chemical resistance, and is also excellent in flexibility and impact resistance, and exhibits strong adhesive strength to a wetting surface. Strength can be imparted to the protective part 3 by mixing various reinforcing materials such as an aggregate 4 and a rubber chip.  Since a surface of the concrete block 1 is covered with the protective part 3 formed of resin mixed with the reinforcing materials, impact resistance and abrasion resistance can be largely improved.

Title: Trigger circuit
Inventor: SANO KOICHI
IPC: H03L7/00
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To obtain a trigger signal whose timing jitter is small. SOLUTION: This trigger circuit makes current (Irfa+Iba) flow to a resonant tunnel diode RTDa for an arm, makes current (Ibt+Irft1) (<(Irfa+Ib)) flow to a resonant tunnel diode RTDt for a trigger, makes the diode RTDa first perform the switching of VL→VH and increases the current flowing to the diode RTDt to (Ibt+Irft1+Irft2) by that. Thus, the diode RTDt is switched VL→VH in the timing of a high through rate of a high frequency input signal and outputs a trigger signal whose timing jitter is small.

Title: Surface treatment device for gravure cylinder
Inventor: SAKAMAKI SEIJI
IPC: C25D17/00
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a device which is capable of rapidly discharging a treating liquid and is small in size and low in cost by disposing a valve disk which opens and closes the liquid drain port disposed at the bottom of a treating vessel and disposing opening/closing means for opening and closing this valve disk on the outside of this treating vessel. SOLUTION: When the surface treatment of a gravure cylinder 1 ends within the treating vessel 10, the air cylinder 21 of the opening/closing means 20 operates to push up the valve disk 26 toward an alternate long and two short dashes line from a solid line state through the liquid drain port 12 via a connecting rod 23. This time is the time of the max. load on the opening/closing means 20 and, if the liquid drain port 12 is opened even slightly, the closing force by the treating liquid pressure is released. Then, the load is small thereafter and, therefore, the valve disk may be rapidly opened by the stable opening action.  The rapid discharge to drastically shorten the discharge time of the treating liquid Q to a retaining tank 15 for the liquid Q may be executed by forming the liquid drain port 12 to a larger diameter and eventually the productivity and the surface treatment quality are improved.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To make an image reader low in cost and small in size by eliminating a moving body without impairing the versatility of a contact image sensor. SOLUTION: A contact image sensor 2 is provided with a slide bearing 12, and since the slide bearing 12 is slid contact with a read shaft 4, the reading range is not disordered. The focal distance of the contact image sensor 2 is kept by abutting the contact image sensor 2 to contact glass 8 by a grounded roller 15 and a leaf spring 16. Therefore, since the contact image sensor 2 is directly provided with a function that is conventionally provided at the moving body, the moving body can be excluded. The casing of the contact image sensor 2 is made of aluminium usually, and is made excellent in rigidity strenght.
